[0029] Example:

[0030] Please refer to Figures 1 to 7 As shown, this embodiment provides an oil filter with an adjustable air inlet 30, including: an oil filter frame 10, an adjustment component, and a toggle plate 201. The inner wall of the oil filter frame 10 is provided with a mounting groove 101, and the bottom of the mounting groove 101 is provided with a plurality of rotating holes 102; the adjustment component is divided into a plurality of first adjustment parts and a plurality of second adjustment parts, the first adjustment part is fixedly installed in the mounting groove 101, and the second adjustment part is rotatably installed in the rotating hole 102, and a plurality of accommodating channels 200 with adjustable sizes are formed between the first adjustment part and the second adjustment part, and the accommodating channels 200 are used to pass oil smoke; the toggle plate 201 is installed on the second adjustment part, and is used to toggle the second adjustment part to rotate relative to the central axis of the rotating hole 102, and the plurality of second adjustment parts are mutually connected in transmission, and the toggle plate 201 is rotated to drive the plurality of second adjustment parts to rotate relative to the first adjustment part, thereby adjusting the size of the accommodating channel 200.

[0031] In this embodiment, if Figure 1 , Figure 2 and Figure 4As shown, the oil filter frame 10 adopts a universal mounting frame for common oil fume purification integrated machines. First, prepare the oil filter frame 10, the adjustment component and the toggle plate 201 and other components. The inner wall of the oil filter frame 10 is provided with a mounting groove 101, and a plurality of rotating holes 102 are accurately provided at the bottom of the mounting groove 101 to ensure that the position of the rotating hole 102 is accurate and the size is appropriate, so as to facilitate the subsequent installation of the adjustment component. The first adjustment part in the adjustment component is fixedly installed in the mounting groove 101, and its firmness can be ensured by welding, bolting and the like. After the first adjustment part is installed, the second adjustment part is installed one by one in the rotating hole 102 to ensure that the second adjustment part after installation can rotate smoothly around the central axis of the rotating hole 102. During the installation process, it is necessary to ensure that the initial position between the first adjustment part and the second adjustment part can form a certain size of the accommodating channel 200 for the oil fume to pass through. Next, the toggle plate 201 is installed on one of the second adjustment parts, which can be connected by a card slot or fixed by screws. After installation, the plurality of second adjustment parts are connected to each other through a transmission device, for example, a chain, gear or other transmission method can be used. In actual use, when the size of the accommodating channel 200 needs to be adjusted, the toggle plate 201 can be manually rotated. The rotation of the toggle plate 201 drives the second adjustment part connected thereto to rotate around the central axis of the rotating hole 102. Since the plurality of second adjustment parts are connected to each other through transmission, the rotation of one second adjustment part drives all other second adjustment parts to rotate synchronously. With the rotation of the second adjustment part, the size of the accommodating channel 200 formed between the first adjustment part and the second adjustment part will change. When the air inlet 30 needs to be increased, the toggle plate 201 is rotated to rotate the second adjustment part in a specific direction to increase the size of the accommodating channel 200; when the air inlet 30 needs to be reduced, the toggle plate 201 is rotated in the opposite direction to rotate the second adjustment part in the opposite direction to reduce the size of the accommodating channel 200, so that the function of the oil filter net of the adjustable air inlet 30 can be realized to meet the demand for the oil fume filtering air intake under different circumstances.

[0032] Further, in some implementations of this embodiment, Figure 4 , Figure 5 , Figure 6 As shown, the first adjusting part includes: a fixed mesh bar 211 and two fixed mesh bar edges 212. The two fixed mesh bar edges 212 are vertically mounted on the fixed mesh bar 211, and the two fixed mesh bar edges 212 are respectively arranged at two ends of the fixed mesh bar 211.

[0033] In this embodiment, the fixed mesh bar 211 has a bottom surface, which is fixed on the inner wall of the oil filter mesh frame 10. The fixed mesh bar 211 is a sheet metal processing part with a symmetrical design. The fixed mesh bar 211 is distributed in two parts. The two parts are relatively arranged on two opposite sides of the oil filter mesh frame 10. The multiple fixed mesh bars 211 in each part are evenly spaced apart. Fixed mesh bar edges 212 are provided on both sides of the fixed mesh bar 211 to guide the formation of the accommodating channel 200.

[0034] Further, in some implementations of this embodiment, Figures 1 to 7 As shown, the second adjustment part includes: a moving mesh bar 221, two moving mesh bar edges 222, two moving mesh bar edges 222, and a gear plate 224. The two moving mesh bar edges 222 are vertically mounted on the moving mesh bar 221, and the two moving mesh bar edges 222 are respectively arranged at both ends of the moving mesh bar 221; the pin 223 is fixed at both ends of the rotation center of the moving mesh bar 221; the gear plate 224 is arranged on the moving mesh bar 221, and the gear plates 224 on the multiple moving mesh bars 221 are meshed with each other, and the toggle plate 201 is rotated to drive the multiple moving mesh bars 221 to rotate, thereby adjusting the size of the accommodating channel 200.

[0035] In this embodiment, if Figures 3 to 7 As shown, the moving mesh bar 221 is a sheet metal processing material with an axisymmetric design. By rotating the installation angle of the moving mesh bar 221, the setting gap between the moving mesh bar 221 and the fixed mesh bar 211 is changed, thereby changing the size of the accommodating channel 200.

[0036] Furthermore, in some implementations of this embodiment, Figures 1 to 6 As shown, the multiple moving mesh strips 221 and the multiple fixed mesh strips 211 are arranged alternately.

[0037] In this embodiment, if Figure 5 As shown, the moving mesh strips 221 are interspersed and arranged at intervals in the gaps between the two parts of the fixed mesh strips 211, and are respectively in contact with the two parts of the fixed mesh strips 211, thereby forming a reliable seal.

[0038] Furthermore, in some implementations of this embodiment, Figures 1 to 6 The toggle plate 201 is fixedly arranged on the middle moving mesh bar 221, and the toggle plate 201 is rotated to rotate the moving mesh bar 221, thereby driving the moving mesh bar edge 222 to move toward the fixed mesh bar edges 212 on both sides.

[0039] To sum up, when using an oil filter with an adjustable air inlet 30, the movable mesh strip 221 is rotated by toggling the toggle plate 201, so that the movable mesh strip edge 222 and the fixed mesh strip edge 212 can be closed or separated, thereby closing or opening the smoke inlet of the oil filter. The combination of multiple fixed mesh strips 211 and multiple second adjustment parts drives the multiple second adjustment parts to cooperate with the multiple fixed mesh strips 211 under the action of the mutual engagement of the gear plate 224, thereby achieving the purpose of adjusting the smoke extraction effect of the oil fume purification machine.

[0040] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
